Traffic Shaping for a particular set of ip's or dhcp range

[ITWORX]

Hi, I`ve searched the forum and found quite a few threads on this topic but without answers. is there currently any way to specify a range of IP's that I wish to shape, e.g. 192.168.1.0 - 20, or specify just the dhcp range or even better use aliases. Currently seems I must manually type every single ip.
